The mede of operation isas follows: Suppose the guide rods raised up and resting 'against the top of the press, the frame with feed board and other appendages, slid back `on the sliders clear of the form, the paper must now be placed on the board and the inking apparatus properly adjusted. The

frame is then slid forward until it is in the position represented in Fig. l. The guide rods, with the clamp c, weights cords &c. is then lowered into their place and adjusted. The pressman then feeds the top sheet into the clamp b, and by a slight pressure on the upper j aw the clamp is latched by the spring catches r, r,` and thus clamps the front end of the sheet, he then runs in the form and makes the impression, the clamp c, has fol?` .lowed the sheet, until it arrived at the edge of the platen, when by the additional pull given by the movement of the cam levers striking against Z, the jaws pass beyond the edge of the sheet, at the same instant the teeth on the edge of the platen marked w, m, striking the catches y, y, sets the springfree and closes the clamp on the margin of the sheet, the pressman now runs back the carriage, bringing the printed sheet fast in the clamp c, until it arrives at g, when it is pressed open, the sheet dropped and the catches y, y, hooked at the same moment.

ready to receive another sheet. When it ar` rives at the point of the frame s, itis raised up until it reaches the edge of the feed ,blankets may bestretched to form a tympan.

Vhen the carriage is run out, the cam le vers are made to assume the position as seen `in the dotted lines at f, Fig. l, by means of a check cord attached to their lower end, and

The form is inked by the motion of carriage operating the rollers, as seen in Fig. 3, by means of a rack and pinion, but as this makes no part of our present claim, an eX- act description may not be necessary.

We have thus described the construction and operation of our improvement, its advantages are 1st a saving of at least onehalf the labor required .to Work a common hand press, in the present mode. 2 securing perfect register by suitable guages on the feed board and clamp I). 3 the inking Will be more uniform than it can be done by hand. 4th it may be attached to any or all of the hand presses now in use, thus doubling their efciency.

What We claim and desire to secure by Letters Pat-ent is- The feeding hand presses automatically, by means of the operation of the clamps, guide rods, cords, Weights, pulleys, catches, and springs, arranged in the manner and for the purposes as above set forth substantially.
